Cup-shaped ear is a common congenital auricle deformity, which mostly occurs on both sides. The deformity is mainly manifested in the upper part of the auricle, where the helix contracts, the helix is curled and adhered to the cartilage of the auricle, and the helix foot moves down, making the helix and its hind foot flatten or even disappear, widening the concha, bending the edge of the helix to the concha, and the auricle is cup-shaped. In severe cases, the auricle is almost curled into a tube. Some friends with serious cup-shaped ears will have an effect if they wear glasses. Plastic surgery for cup-shaped ears is very necessary. Plastic surgery should be done sooner rather than later, usually at the age of six. Note: 1. Ear curl. In light cases, the helix itself is folded, and in heavy cases, the whole auricle hangs down to cover the ear hole. Second, the auricle leans forward, that is, the ear is flared, but different from the simple ear deformity, cup-shaped ear plastic surgery needs targeted treatment. Third, the auricle becomes smaller, mainly because the length of the auricle becomes shorter. Fourthly, the position of auricle is low, which can be improved by cup-shaped ear plastic surgery, especially in severe cases, often accompanied by maxillofacial deformities. 3. Incision: First, perform local anesthesia and disinfection, and make a horizontal incision on the back of the upper part of the helix at the most obvious place of the anterior fold, reaching the cartilage surface; 2. Cut off the cartilage: separate from the incision to expose the upper cartilage of the auricle, so that the upper skin of the auricle is sleeve-shaped and the upper cartilage is detached. Then cut the auricle cartilage from the most obvious part of the auricle, shift it upward and straighten it, sew it in a proper position to form a new spiral, sew up the skin incision, shape it with a fixed suture, compress the postoperative wound, and finally do the postoperative treatment as usual.
